Unlike other memory storage mediums, these
new 'Superman' memory crystal can store up to 360 terabytes per disc, thermal
stability up to 1000°C and a practically unlimited lifetime. A press release
states that "the data is recorded via self-assembled nanostructures
created in fused quartz, which is able to store vast quantities of data for
over a million years."
"The
information encoding is realised in five dimensions: the size and orientation
in addition to the three dimensional position of these nanostructures. The
self-assembled nanostructures change the way light travels through glass,
modifying polarization of light that can then be read by combination of optical
microscope and a polarizer, similar to that found in Polaroid sunglasses."
